PC automatically shuts down following a Windows error
I can attempt a different CPU because I'm planning to microcenter today.
Purchase the most affordable option that fits the chipset. Microcenter also offers a repair facility if you wish to send your computer there.
I need to check their fees.
If your RAM isn't supported, I'd consider swapping it out, unless you already own one. Try installing a 4GB module to check if that fixes the issue.
